Definitions
- the invention relates to a device for aliquoting and filtering blood. More particularly, the device of the invention makes it possible to aliquot, filter and dispense small amounts (microliters) of blood.
- Many biomedical analysis techniques require the filtration of a small amount of blood to separate the plasma to be analyzed from blood cells (mainly red and white cells).
- a known method for performing such filtering is to fill a container (such as a pipette cone or a capillary) with a given volume of whole blood with whole blood, then dispense the contents on a filter to effect the separation and recover the separated plasma. solid components of the blood. Therefore, there are two distinct steps - three if you also consider taking blood from the patient's body.
- KABE Labortechnik sells microtubes, out of which a calibrated volume capillary tube protrudes (see a brochure on the Internet: http: //www.kabe- labortechnik.de/download/kapillarblut_en.pdf).
- a determined volume of blood (of the order of 100 .mu.l) using such a device and deposit it on a filter, the procedure is as follows. First, a patient's finger is pricked with a lancet, and a droplet of blood is taken out; then, approaching the droplet the end of the capillary duct, maintained in a horizontal position. The tube fills gradually according to the capillary flow. Once filled, the microtube is brought into vertical position to empty the capillary duct on a filter, the emptying being assisted by slight shocks or vibrations.
- the operation is relatively complex and does not prevent any risk of contamination of or through the blood.
- the capillary forces retain about 25% of the liquid in the conduit, which affects the accuracy of the aliquot. It is also possible to replace the microtube with a pipette pear, so as to allow emptying of the capillary duct by applying an overpressure. This solution allows a more complete emptying, and therefore a more precise aliquoting, but the other disadvantages of the device remain.
- the invention aims to solve at least some of the disadvantages of the prior art.
- the device of the invention allows a precise aliquotage of the blood and a substantially complete dispensation to a filter, which is performed automatically, by capillarity.
- a blood aliquoting and filtering device comprises a blood collection element; a capillary duct having a capillary force greater than that of said collection element and in fluid communication with it; and a dispensing element having a capillary force greater than that of the capillary duct and in fluid communication with it; said dispensing element having a filtering device for separating blood cells from the plasma.
- the functions of aliquoting, dispensing and filtering, or even sampling can be integrated in the same planar device of very simple structure.
- said filtering device may be adapted to become saturated with globules after filtering a volume of blood depending on the hematocrit content of said blood, but in any case less than the capacity of said collection element and said capillary duct; visual cues being provided, allowing to estimate by simple inspection the volume of liquid present in said capillary duct.
- the hematocrit rate of said blood can be determined from the estimate of the volume of blood remaining in the capillary duct after saturation of the filtering device.
- the device may also comprise, downstream of said filtering device, a detachable element made of material absorbing blood plasma and able to retain, after drying, the proteins contained in said plasma. In this way, a plasma sample can be taken directly from the patient at home. After separation of the device and drying, the absorbent element may be mailed to a laboratory for analysis of plasma proteins stored therein.
- FIGS. 1 and 2 respectively, a plan view and in section of the aliquoting section and dispensing blood from a device according to a first embodiment of the invention
- - Figure 3 a sectional view of the aliquot section and dispenses blood from a device according to a second embodiment of the invention
- FIGS. 4A to 4E filling the aliquoting section and dispensing blood from FIGS. 1 and 2
- FIGS. 4F to 41 the emptying of this same section
- FIG. 5 the application of a device of the invention to the measurement of the hematocrit level of a blood sample.
- the aliquotage and blood dispensing section of Figures 1 and 2 has a planar structure and is made, for example by molding or machining, from a member 100 of hard or soft plastic material.
- a soft plastic such as polydimethylsiloxane (PDMS) or a silicone is particularly preferred for the implementation of the invention as well as a plastic moldable or machinable transparent and preferably hydrophilic.
- a well or bowl 1 intended for the collection of whole blood to be aliquoted and filtered, and a capillary conduit 2 closed, in fluid communication with the well 1.
- a cap must be placed above the duct 2.
- the conduit 2 debunks in a hole 30 which passes through the element 100.
- a filter membrane typically paper.
- this membrane may be an absorbent element 4, whose function will be explained later.
- the internal volume of the collection element 1 and the capillary duct together determine the quantity of blood that can be dispensed.
- This volume is generally between 10 .mu.l and 1 ml, and preferably between 50 .mu.l and 500 .mu.l. It is preferable, in order to optimize the accuracy of the aliquoting, that the volume of the duct 2 is much greater than that of the well 1: for this reason, said duct may be spirally wound or arranged in a coil. Overall, the device has dimensions of the order of centimeters.
- the collection well 1 may have a diameter of the order of 1 - 10 mm, and the capillary duct have a section of a few mm 2 area of several centimeters in length; for example, it is possible to envisage a duct of rectangular section 0.5 ⁇ 2 mm, with a length of 7.5 cm, ie an internal volume of 75 ⁇ l.
- the capillary duct 2 and / or the well 1 may contain, before use, various liquid, gel or dried compounds such as anticoagulants for blood such as ethylene-diamine-tetraacetic acid (EDTA) 1 of the agents agglutinating globules such as lectin, or coagulation provoking agents such as prothrombin.
- EDTA ethylene-diamine-tetraacetic acid
- the internal walls of the duct 2 to be induced by a gel which renders said walls hydrophilic and which progressively releases an anticoagulant during the filling of the capillary, thereby preventing any start of coagulation.
- droplets of blood S may be deposited one by one into well 1, progressively filling it.
- the blood S begins to enter the conduit 2, and is sucked there by capillarity.
- the conduit 2 is completely filled, the blood S reaches the filter membrane 3 via the hole 30, and is sucked by the latter, which has a capillary force substantially greater than that of the conduit 2.
- the amount of liquid inside the device is known precisely: there is aliquotage.
- the aspiration of the blood S by the filtering membrane 3 continues until the complete emptying of the device (FIGS. 4F to 4I): there is therefore dispensing of the aliquoted quantity of blood.
- the filter membrane 3 is adapted to retain the blood cells and let the plasma pass. The latter can therefore be collected downstream of said membrane.
- the blood plasma can be collected by an absorbent element 4 in contact with the filter membrane 3 and detachable from the device.
- Absorbent element 4 imbibe plasma, then it is separated and dried. At this point, it can be sent to a laboratory for the biochemical analysis of the proteins that remain stored there: this application is described in detail in the patent application in France FR 07 07709 filed November 2, 2007.
- the filter membrane 3 may be sized to saturate with blood cells before the complete emptying of the device.
- the exact amount of blood that can pass through the filter before all its pores are clogged with blood cells depends on its hematocrit level. This rate can therefore be estimated by measuring the amount of liquid remaining inside the device after the partial emptying of the latter. This measurement can be performed approximately with the help of visual cues (lines R1 - R4 in Figure 5) which is provided with the device. It is understood that in this case the planar element 100 must be transparent.
- the plasma can be collected in a tank disposed downstream of the filter 3.
- a network of micropiliers can also constitute a dispensing element adapted to the implementation of the invention.
- it may be micropiliers made of silicon, having a square section of 50 ⁇ m ⁇ 50 ⁇ m, a separation of 50 ⁇ m and a height of 200 ⁇ m.
- These micropiliers can be induced by suitable chemical substances (for example antibody-antigen binding, streptavidin) to carry out pre-treatment of the blood, for example capturing analytes (Arn, proteins) which can then be detected through the device or collected for analysis.
- FIG. 3 shows a particularly advantageous variant of the device of the invention, comprising a collection element 10 constituted by a matrix of microneedles 11, preferably hollow, and by a reservoir 12 integrated in the planar element 100 and disposed below. of said matrix.
- the microneedles 11 are adapted to pass through the skin of a patient, for example at the end of a finger, and extract a small amount of blood; they must therefore have a length of at least 200 ⁇ m, and preferably 1 to 2 mm, to penetrate into the dermis. In this way the risk of infection for the patient and contamination of the sample taken is minimized.
- blood extraction, aliquoting and dispensing are performed by a single operation.
- a bonding region 50 for example in the form of a ring, surrounds the collection element. In the case of a blood sample, the patient presses his finger at said collection element, if necessary after having stung with a lancet (if the device does not include microneedles).
- the sticky region 50 allows the formation of a seal between the finger and the device, avoiding any blood dispersion and associated biological risks and prolonged contact between the blood and the air, which can accelerate coagulation) .
- the patient keeps his finger on the device during the entire filling phase.
- the conduit 2 When the conduit 2 is full, it removes the must, which allows a quick emptying of the device by capillarity: indeed, as long as the finger is present, the emptying is slowed down and limited to the blood flow rate, whereas when the finger is removed the flow is controlled by the capillary force output of the device.
- the sticky seal does not prevent the finger massage that helps the extraction of blood.
- the collection element may also comprise more or less flexible abutments that help to massage the finger locally, thereby facilitating the flow of blood from the finger to the device.
